Args:
input_file_path1 (str): Description for the first input file path. File type: input. `Sample file <https://urlto.sample>`_. Accepted formats: top (edam:format_3881).
input_file_path2 (str) (Optional): Description for the second input file path (optional). File type: input. `Sample file <https://urlto.sample>`_. Accepted formats: dcd (edam:format_3878).
output_file_path (str): Description for the output file path. File type: output. `Sample file <https://urlto.sample>`_. Accepted formats: zip (edam:format_3987).
properties (dic):
* **boolean_property** (*bool*) - (True) Example of boolean property.
* **binary_path** (*str*) - ("zip") Example of executable binary property.
* **remove_tmp** (*bool*) - (True) [WF property] Remove temporal files.
* **restart** (*bool*) - (False) [WF property] Do not execute if output files exist.
Examples:
This is a use example of how to use the building block from Python::
from biobb_template.template.template import template
prop = {
'boolean_property': True
}
template(input_file_path1='/path/to/myTopology.top',
output_file_path='/path/to/newCompressedFile.zip',
input_file_path2='/path/to/mytrajectory.dcd',
